JERSEY, ASSIGNOR, BY MESNE ASSIGN- PIPE i Application led September 15, 1924, Serial This invention relates to tobacco pipes. Among the objects ofthe invention are to improve the construction of such pipes; to

provide for keeping them cleaner and sweeter; to adapt them' to be readily cleaned and aired; to permit the 'optional use of means for eliminating nicotine during the operation of the pipe; to construct the pipe in such a manner-as to permit the various parts tov be formed of a Wide range of materials and to be stamped,molded, cut or otherwise shaped; and, generally, to provide a novel construction and arrangement of pipe and to improve the smoking qualities thereof.

The invention resides in the construction, combination and arrangement of parts and in the details of construction as hereinafter described and claimed, it being understood that many changes in the construction and ar rangement of parts and in the details of the pipe may be made within the scope of the claims and as indicated by the variations between the different claims, without departing from the spirit or the scope of the invention.

Referring to the construction yillustrated 7o 1n Figs. 1,l 2, 3, 4, 5 and 6, reference letter A indicates the bowl; B the stem formed of two separable elements; and C the clip by which glliedbowl and stem elements are held assem- The-,upper element 2 illustrated in Figs. 2, -4 and 5, is formed in its `un er or inside face with a smoke channel 1 which extends from' the mouth end of the stem to the bowl end thereof.' The stem eleso ment 2, preferably, is thickened as it approaches the bowl and is then formed with a slight downward bevel 3, best shown in Figs. 1 and .5, on which the bowl A rests. The bowl recelvmg portion 3 of the element 2 is prog5 vlded wlth a circular opening 4 into which the smoke channel 1 opens.

The bowl A as shown in Fig. l5 is provided with a tobacco receptacle 5 which extends through the bowl from top to bottom, and on 90 its lower end the bowl isprovided with an annular flange 6 which is shaped to fit into the opening 4 in the stem element 2.

The lower element 7 of the stem B preferof the stem B, as

ably is fiat on its upper surface `and serves, e5

functionally, to close the lower end'of the smoke channel 1 when the stem is assembled. On its lower face, as best shown in Figs. 8 and 5, the stem element 7 is formed with a circular groove 8 and a short sharp bevel 9, 100

' the bowl A,the two ends of the ring 14 be.-

.ing

between'thel shoulders 10 and 11 in Fig. 3 and serves to provide a vbeveled guide channel by which the lower ends 12 of the spring clip C are guided into their position-'within the circular groove 8.'

1 The clip C preferably is formed -with the circular portion 14 which iits into a groove 15 held in assembled position by thelink 17. In assembling the construction illustrated in Figs. 1 to 6, the upper element 2 is inserted over the arms 12 of the l12a of the arms 12,

litted over the flange lower stemjelement 7 is placed iiat against the element 2, with the outwardly bent ends endsof the beveled channel 9 in Fig. 3. In

this position, the stem elementf7 projects beyond or .overlaps the element 1,l and by now pushing the element 7 in the direction of Vthel in opposite directions without disassembling the pipe vand by this simple action, the smoke channel of the element 2 is exposed for cleaning. .The three parts of the pipe can of course be easily disassembled for thorough. airing and cleaning.

' I prefer to shape'the stem elements 2 and 7.

' I- so that, as shown in Fig. 1, they tend normally to spring slightly apart at the mouth end of the stem as indicated at 18. This enables the smoker to use the pipe either with the two stem elements pinched tightly together ora hot smoke, or to` procure a cooler smokel by drawing in a regulatable amount of air through the ends of the stem elements which are nearest the mouth.

The construction described also permits the smoker if desired to place a sheet of paper indicated by 19 .between the upperand lower stem elements. Anykind of paper can be used for this purpose,

.. of the paper as any projecting edges vof the paper can be readily torn away.v The use be called a roughly absorbent bottom or'both the bowl of the pipe and the smoke channel 1 throughout its len sorbed or eliminated from the smoke by the nicotine eliminator 19. -I

It is found in practice that when the paper 19 is used, it tends to assume a wavy eii'ect along the smoke channel as shown in Fig. 9

. due to the action of the heat and moisture.

In Fig. 7, I have'illustrated a modified arrangement of the clip' C using an endless ring of wire in which. 14 is a ring itted pern'anently in the groove 15, and 14" are twisted portlons forming downwardly, inwardly and upwardly bent spring arms 14 which serve clip. and the hole 4 .is 6 of the'bowl. Then the'` -just resting vwithin the position 19 serves to provide what might h, andl it is found in practice that the nicotine or tobacco oil is ab- -the same function as the arms12- in Fig.- 5.`

The remaining construction of the pipe is'the same as illustrated in Figs. 1 to 5 and when 'the clamping device of Fig. 7 is used in place of that shown in Fig. 1the. parts are assembled in the 'same manner as previously described'.

The modiied construction illustrated in Figs. 8,9,10 and l11 comprises a bowl A having a closed lower end 21 and athreaded'low'- er portion 22 which is designed to engage an opening 4a in the upper stem element 2a and also to engage the threads of an opening 4b in 'thelower stem element 7a.

In this construction, I preferto employ, -as a means of preventing any leakage of air and of holding the lstem elements, against relative rotation, a rib 24 stem element 2a, but this rib and groove may be omitted ifv desired. The rib 24 starts on one side ofthe mouth end of the pipe and ex tends longitudinally of the- 'stem element around the bowl and then back' along the otler side of the stem element of the mouth en At its lower end the which, as shownin Fig. 10,- its into corresponding groove 25 inthe upper bowlis provided with one or more elongated smoke slots 26 designed i to be registered with the smoke channel 1a in the stem element B.

In assembling the structure of Figs. 8 to 11',

the two stem elements are fitted together with the rib 24 engaging the groove 25. The bowl is thon screwed .down through the bowl openings in the two stem elements, thus serving t0 hold the three elements 'of the pipe in assembled position.

The construction modified, illustrated in Figs. 12 and 13, is adapted to be formed of 'any suitable metal or other material.

I'` prefer to 2d integral with the bowl A2.

Clamped Orotherwise suitably secured to the mouth ends of the stem elements 2d and 7d are lips 30 and 31 formed of anysuitable c0111- or other material.

form the upper stem element The upper ste-m element 2d preferably is three longitudinally extending, which at their bowl ends are reenforced by integral ribs 32 lcontinued upwardly to form three cooling flanges 32".

The interior ofthev bowl A2 is lined with a terial or compound indicated by 33 and within that is a metal cylinder 34 which forms the cylinder of any suitable heat insulating 'maanysuitable pipe composition Ior other Ina-y terial.

The improved pipe structure as a wholepresents a novel and pleasing appearance.

Dilerent'kinds of bowls can be readily used with a single set. of the stem elements. The

pipe provides a cool, sweet smokeand is readily cleanable.

Since certain changes may `bemade in the above article and different embodiments of4 the invention could be made without departing from the scope thereof, it is'intended that all matter contained in the above descrlptlon or-shownv in the accompanying drawing shall` be interpreted as illustrative and not in a limiting sense. It is also to be understood that the follow- I ing claims are intended to cover all of the generic and s ecific features of the invention herein descri ed, and all statement-s of the Ascope of the invention which, as a matter of language, mightbe said to fall therebetween.
